The EM-12 is a durable case that snaps onto a Microsoft Surface Pro, transforming it into a touch screen speech generating device. Purpose-built for augmentative and alternative communication, the rugged case has a screen protector for added security. It comes with our symbol-based TD Snap app and text-based Communicator 5 software depending on your needs, or to enable progression from symbols to text as literacy skills evolve.

Eye tracker accessory

The EM-12 works seamlessly with our EyeMobile Plus eye tracking bracket for hands-free communication. This optional accessory enables eye, voice and switch scanning control with built-in eye tracker, microphone, speakers, mount plate and kickstand, plus its own battery for prolonged use. Adding the EyeMobile Plus bracket accessory allows control of the EM-12 with your eyes.
